Synopsis
At a formal evening gathering, Constance, a straightforward viscount's daughter whose honesty has left her with little influence, encounters Scarlet Castiel—the notorious noblewoman executed a decade earlier. Scarlet's return is tied to unfinished business, and Constance becomes involved in investigating the hidden forces behind it. What begins as a wary alliance develops into a shared pursuit of the conspiracy still shaping their society.
